Logger

自用的 Android/Java 日志打印组件，面向接口编程，使用接口对各模块进行解耦，增强对第三方库的管控，底层可无缝切换底层的具体实现。默认实现了android.util.Log、System.out.println及https://github.com/orhanobut/logger 。

    allprojects {
        repositories {
            maven { url 'https://www.jitpack.io' }
        }
    }

    dependencies {
        implementation 'com.github.gzu-liyujiang:Logger:版本号'
        debugRuntimeOnly 'com.orhanobut:logger:2.2.0'
    }

public class MyApp extends Application {
    
    static {
        if (BuildConfig.DEBUG) {
            // 若使用打印器，需添加依赖（runtimeOnly 'com.orhanobut:logger:2.2.0'）
            Logger.enableConsolePrinter();
            //Logger.setConsolePrinter(log -> System.out.println("替待默认的打印器：" + log));
            Logger.addOtherPrinter(log -> System.out.println("诸如，可以将日志保存到文件：" + log));
        } else {
            Logger.disableConsolePrinter();
        }
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Logger.print("Application onCreate");
    }

}

        Logger.print("测试1");
        Logger.print(new RuntimeException("测试2"));
        Logger.print("当前类：%s", getClass().getName());
